LOCKING DEVICE.

Application tiled December 18, 1926. Serial No. 155,628.

This invention relates to certain new and useful improvements in locking devices of that type especially designed for controlling a mechanism located remote from the key actuated lookin member, which heretofore has consisted, ot a mounting body or shell,

a locking barrel mounting head having) a lock bolt mechanism and being slida ly mounted in the shell and having mechanism to be locked connected therewith by a cable or the like and a tumbler cylinder rotatable in the locking barrel mounting' head, the cylinder normally Securing the mounting head fast in the mounting shell.

One of the objects of this invention is to materially simplify the key actuating locking mechanism by the elimination of the locking barrel mounting head and it lock bolt mechanism.

Another object of this invention resides in the provision of an improved locking mechanism wherein the tumbler cylinder is slidable and rotatable within limits in the body or shell and controls the Bowden wire or other means connected with the element to be locked.

A. further object of this invention resides in the provision of an improved lockin mechanism of the character describe 30 wherein a helical or twisted member is carried by the tumbler cylinder to impart simultaneous longitudinal and rotary movemerli;-J thereto in the shell when released by its e With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention ma be made as come within the scope of the c aims.

In the accompanying drawing, I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a viewtaken transversely through the locking device embodying my invention, illustrating the same in locked position, parts thereof being in section and parts in side elevation;

Figure 2 is a view similar to Figure 1 illustrating the lock as in unlocked position with the body casing rotated through ninety degrees;

Figure 3 is a transverse, sectional view through Figure 2 on the plane of the line 3-3, and

Figure 4 is a transverse, sectional view lllrugh Figure 3 on the plane of the line Referring now more particularly to the accompanying drawing, in which like numerals designate like parts throughout the several views, 5 designates a body or shell member which may, for convenience and economy in manufacture, be die cast or machined from suitable metal, such as brass, and is adapted to be mounted at the instrument board or panel of an automative vehicle when applied thereto. The rear portion of the shell is bored orchambered, as at 6, and its forward portion is bored or chambered, as at 7, a plate or washer 8 being longitudinally movable in the bore 6 and has one end of a Bowden wire or other means 9 leading to the element to be locked, not shown, connected therewith, as at 10. Au expansile spring 11 is confined between the washer 8 and a plug 12 is threaded into the inner end of the shell to close the bore 6 and through which the Bowden wire passes and to which a casing or tube 13 for the Bowden wire is suitably secured, as at 14.

The spring 11 normally exerts a pressure on the washer 8 to tend to move the same into the bore 6 and with it the Bowden wire 9 to unlock the element, not shown with which the wire is connected and a key actuated means is mounted in the bore 7 to operate the washer against the spring 11 and move the Bowden Wire 9 to element locking position. The ke actuated means consists of a plug or tum ler cylinder 15 which ma be of substantially conventional construction having a series of tumblers 16 therein adapted to cooperate with a key 17, shown in dotted lines in Fi ure 1, which is adapted to be inserted in t e key slot 18 of the cylinder and through the slots of the tumblers, the tumblers being urged to engage in an elongated slot 19 in the shell 5 in register withithe bore 7 by springs 20, best shown in Figure 3, to lock the c linder against rotation. A slot 21 is forme in the shell 5 in communication with the bore 7 diametrically opposite the lockin slot 19 to permit the ends 22 of the tum lers 16 to move thereinto when the key 17 is removed.

The cylinder 15 has its forward end portion 23 slightly reduced to pass through a bore of like diameter in a cap 24 secured over the flanged end 25 of the shell, the shoulder 26 formed at the inner end of the reduced portion 23 providing a stop abutting the cap 24 to limit the outward movement of the cylinder. The inner end portion 2T of the cylinder is preferably reduced in diameter and is slotted or recessed, as at 28, to receive the inner end of a tail piece 29 preferably formed from a length of metal having its outer end twisted to form a helical portion 30 which passes through a slot 31 in the partition or Wall 32 supporting the bores 6 and 7. The tail piece is made fast to the cylinder end 27 by a rivet or screw 33 passing through an aperture in the end of the tail piece fitted in the slot 28 and threaded in the cylinder, as at 34, the tail piece imparting longitudinal movement to the cylinder as it is rotated by its key.

The tail piece 29 is so twisted that its ends are at approximately right angles to so dene the limits of rotation of the cylinder and with the" parts in the position illustrated in Figure 1, the element, not shown, with which the Bowden wire 9 is connected is in locked position. The key 17 is then inserted, the ends 22 of the tumblers moving into slot 21 as the key passes therethrough to unlocking position when the tumblers are drawn into the cylinder with their ends within the peri hery thereof, as illustrated in Figure 3. The key 23 is then turned to rotate the cylinder, the tail piece assisted by the spring 11 moving the c linder outwardly to its position shown in igure 2, the spring 11 moving the washer 8 and the Bowden wire connected therewith into the shell to unlock the element, not shown, connected with the Bowden wire. When the cylinder is in its outermost or unlocked position, the key may be withdrawn if desired, a slot 35 in the wall of the shell 7 i permitting the tumblers to move thereinto as the key is retracted.

To lock the device, the cyclinder is pushed inwardly against the spring 11, the tail piece 29 rotating the same until it reaches its inward limit of movement when the tumblers align with the slot 19 and are moved thereinto by their springs to lock the cylinder against movement in the shell. The cylinder is thereby locked against longitudinal movement by the helical member which structurally prevents such movement unless accompanied by a rotar movement.

The spring 11 being o strong construction to insure its operatin the mechanism, not shown, connected wit the Bowden wire 9, causes the cylinder to quickly move outwardly as the tumblers are retracted by the key and this movement, assisted by the normal tendency of a person to twist the key whenin place, is translated to a rotary movement by the helical member.

From the foregoing description taken in connection with the accompanying drawing, it will be readily apparent to those skilled in the art to which an invention of this character appertains that I provide a novel and improved locking device which is very efficient and practical in operation and which reduces the number of parts necessary for its operation, thus effecting a material economy in construction.
